It took me about two hours to get everything together and working. Just as I was about to test it out the finished product slipped from my hands and landed on the concrete steps. As a result one vane of the windmill was broken in half. I am now trying to cobble a “flower” windmill vane to my project.

A great educational toy for future scientists and anyone interested in alternative energy resources. My 10 year old son put this together without any help. It works great and is a good value at $16.

The directions tell you to add water to a bottle for stability, but it doesn’t work very well if it is truly windy outside. And, you need a lot of wind to get the thing going. Our bottle tipped over almost immediately and got the LED light wet-apparently ruining it–so we never got to see the windmill light it up. Filling the bottle with sand or dirt would have been a better suggestion. By following the directions I wasted 13 dollars!

I bought this the other day after seeing in at the Marin Headlands Visitor Center at Rodeo Beach near SF. The kit is relatively easy to build. The motor case cracked a tiny bit when we inserted the motor into the housing. It looks cool. The biggest problem is that you need a good bit of wind to make the thing spin. We found you could flick the propeller to start it, but it needed a stiff breeze to keep it going. Also, you need to put some ballast in your soda can or it will fall over. We filled ours with water and froze it for a more solid base. Cute toy, but we probably won’t buy another. Next, we’ll try mounting it on a long pole to get more elevation, and hopefully more wind.
